Letters Patent No. 83,464, dated October 27, 1868.

IMPRQVED CAR-COUPLING.

The Schedule referred to in these Letters Patentmand making part of the same.

To whom tt may concern:`

l the other, and the'coupling-link being released Figure 3, plan view, transparent, showing arrangement of interior parts. i

Letter A, central portion of the connecting. or bdraught-bar.

B, the lower portion, and containing interior parts duplicate to those in A.

C, ca'p upon the top of and protecting the small parts'in A.

D, connecting-link uniting the two bars A.

e e', hooks,the one in the mouth or throat of A, the other in that of B.

ff', spring-bars or keepers, situated one above the a otherone in A, one in B.

g g', two spindles, the enlarged ends of which bear against the ends of the keepers f f.

h It', pins, which rise into slots in the under side of ff', and keep them from being carried too far forward by the Vsprings 't t. V

i t, spiral springs on the spindles y g', and, being compressed when put in place, their force will act on the upper edge of the inner end of the keepers ff', thereby throwing the outer bevelled ends, z z, upon the hooks e e', and thus prevent the link D from being detached.

j j', holesin A and B for one end of the spindles y g, as shown in iig. l.

It, a short link connecting fand f', so that f shall be raised whenever f is.

l, a staple by which any one Wishing to unshackle the cars can raise both f and j".

O, convex lips of the mouth of the draw-bars.

'm mf, projections on the under side of f and f', which, rising with f and f when any one lifts l, releases the link l), and the cars are disconnected.

The object of my invention is to provide a shackle for railroad-,cars that will connect of themselves when brought together, and shall securely keep united under ordinary circumstances, but be so constructed that when one or more cars run ofi' the track, they shall disconnect automzttically, or any car that runs ofi' shall disengage itself ii'om thoseremaining on the track.

By examining the drawings in iigs. l and 2, it will be seen that when one car is raised vertically mue-h above the one with which it is connected, the link I), vbearing upon the outer portionof the lip in the mouth of the bar A B C, raises the keeper f, and the link l) is at once free.

What I claim as of my invention is f The levers or keepers f, the pins h, the spindles g, the springs t, the staple l, the hooks c, and link D, all ,arranged and combined substantially as and to operate for the purposes specified and set forth.

In testimony whereof, I have signed my name to this specification inthe presence of two subscribing witnesses.
